Basically, JRE is a set of software used to run another Java software. It is a part of the Java development kit (JDK) but you can also install it separately. JRE, along with JVM (Java Virtual Machine) and JDK allows Java developers to build powerful Java applications.

Hence, as a Java developer, you must have JRE installed on your local systems. If you haven’t done that yet, don’t worry. In this exclusive guide, I’m going to present the step-by-step procedure to install the latest version of JRE on your Windows. So, let’s start.

How to install JRE for Windows?

Let’s look at JRE installation steps. In the first step, launch your default browser and visit the official website of Java i.e. java.com. At the top of the home page, you will find the option of Free Java download. Click on it.

On the next screen, click on Agree and start the free download.

If you’re using IE 9 for this purpose, it will ask you to Run, Save, or Cancel. Click on Run. This will automatically start the download process.

If the download is successful, you will receive a message at the bottom stating that your download is successful.

Now, when the User Account Control screen appears, click on the Continue button.

After this step, you will land on a screen asking you to install a free Yahoo toolbar. It’s not of our use. Therefore, make sure to untick that option. Click Next.

On the next screen, accept the license agreement and click the Install button.

This will take a few minutes, no matter how fast the internet you’re using. During this process, you will see an array of applications that will use this Java Runtime Environment.

Congratulations, you have installed the latest version of JRE on your Windows. But wait, the installation process isn’t over yet. After the previous step, you will need to relaunch your browser. For this, just tick the box stating Restart my browser now to complete the installation.

Upon relaunching, click on the Verify Java Version button.

Once verified, you can start working with the JRE’s latest version.

What does the Java Runtime Environment consist of?

JRE consists of the following:

  1. Deployment technologies like Java Web Start and Java Plug-in.
  2. Some user interface toolkits like print service, sound, abstract window toolkit, etc.
  3. Various integration libraries like Interface Definition Language, Java Database Connectivity, Remote Method Invocation, etc.
  4. JVM like Java HotSpot Client and Server Virtual Machines.

Wrapping up

So, this is how you can install any version of JRE on Windows following the above-mentioned steps. JRE is what you get when you install the Java software. And this JRE is responsible for the proper execution of your program.

To summarize its working, read this. 

The bytecode established for your “.java file” is kept in a “.class file”. And JRE can read only the “.class.file”. After reading it, JRE converts the bytecode stored in the “.class file” into the machine code. As a user, you see this machine code on your screen.
